Detailed Description
The QEditorFactory class is used to create editor widgets
for QVariant data types.
Each editor factory provides the createEditor() function which
given a QVariant will create and return a QWidget that can edit
that QVariant. For example if you have a QVariant::String type, a
QLineEdit would be the default editor returned, whereas a
QVariant::Int's default editor would be a QSpinBox.
If you want to create different editors for fields with the same
data type, subclass QEditorFactory and reimplement the
createEditor() function.

QWidget * QEditorFactory::createEditor ( QWidget * parent, const QVariant & v ) [virtual]
